Difference between A-Spec and non-A-Spec suspension?

Could some folks chime in and describe both the subjective and objective differences between the suspensions on the A-Spec and non A-Spec TLXes? I'm wanting a slightly sportier suspension and wondering, would swapping in some A-Spec parts be the best way to achieve that? (I read that it's a little stiffer).

I suppose I should have test driven the A-Spec, I did not.

most of the time; it's just re-valved shocks to provide firmer rebound and compression.
it would be a great upgrade for the NON-Aspecs
might want to look into if the springs are different...?
you could grab the whole assembly.. shock/spring combo!

I had the 15 TLX and now 18 Aspec both in AWD V6. I had H&R sport springs on the 15 and swapped them to the 18 when I upgraded. The 18 struts/shocks handle the springs much better than the 15. The 15 felt a little bouncy and bumps were more harsh. With about 200lbs in the back of the 15 it felt like how the Aspec now feels. Much more controlled. Softer over bumps. Very pleasant for a lowered car. That tells me the springs were overpowering the 15 struts/shocks but the APSEC is a perfect match for them. And it is not because the struts were worn out after 2.5 years. The 15 had a strong rebound bounce over bumps on the freeway from day one. I put the springs on the 2015 at about 6 months old.

I'd definitely like to hear more about this subject from those with experience. Was considering buying an aftermarket coilover system but would be great if the ASpec version performed well. I'm FWD 2.4L.

Using Car and Driver as the source. The difference between the V6 A-spec and other v6 models.........
  • Rear anti roll bar is increased from 24.7 to 25.4 mm.
  • Dampers have revised valving teamed with higher spring rates and reworked bushings to deliver sharper responses and reduced body motion.
Looking at AcuraOEMparts.com shocks, springs, and roll bar are roughly $1000 before install.

I'm not sure how much of a difference that would make on a non AWD car though. The SHAWD does add to the handling. Would have to compare A-SPEC and FWD V6 on slalom or corner G's pulled.

To be honest Chris if you are looking for better handling Id suggest a mild drop with lowering springs on stock shock. That will stiffen up your suspension, lower the center of gravity, and still provide a fairly compliant ride when not pushing it. I also think it looks better when you minimize the wheel well gap.

Drawbacks? Front end will probably scrape on steep driveways, you'll need to get it aligned and even then you will probably get less miles out of your tires, and those train track crossings your accustomed to fly over you'll start to slow down a bit.

Thank you for the information Terdbath - I feel like the TLX is already lower than an ordinary car - what about slightly stiffer springs without lowering?

For many years, 15" wheels were the normal size for typical "family sedans" like the Toyota Camry, so, I feel like the 18" wheels on my TLX already look "premium" / give the appearance of a narrow wheel well gap, and I like the distance from the wheel to the well to be the same on the top as it is on the sides. So, while I understand multiple reasons why some folks like to "drop" their TLXs, I ALREADY find there are places where I drive almost every day that I have to take slow to prevent the front of my car from scraping. So, I'm more keen on the idea of a sportier suspension without lowering.
